To all 'whom t may concern.'

Be it known that I, JAMES B. GURNEY, a citizen of the United States, residing at Collinsville, in the county of Dekalb and State of Alabama., have invented certain new and use-ful Improvements in Churn Dashers; and I do hereby declare the followingy to be a full, clear, and exact descrip-tion of the invention, such as will enab-le others skilled in the art to which it appertains to make and use the same.

The present invention has relation to churns and more particularly to the agitating means whereby the butter cysts are broken up during the process of churnin In accordance with the present invention, the ordinary and well known form of reciprocating dasher embodying a stati:l and arms has an auxiliary dasher of peculiar formation applied thereto, the same comprising a spider, and rotary agitators mounted thereon, the same being grouped about the stati' and inclined thereto whereby to have an automatic rotary movement imparted thereto as the dasher is reciprocated.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

lVhile the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet di'erent conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application,

Figure 1 is a perspective view of a well known churn dasher having the improvement applied thereto,

Figure 2 is a top plan view of the auxiliary dasher,

Figure 3 is a front view thereof, and

Figure 4 is a detail view of a modified form of hub for the churn dasher.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The numeralV 1 designates the ordinary stall of a reciprocating dasher of well known form and having a head at its lower end comprising arms 2.

The auxiliary `dasher comprises a spider embodying a hub 3 and arms 4 radiating from the hub and havingtheir extremities inclined to give the desired set to the-rotary agitators. The hub 3 and arms 4 constitute integral parts and, in practice, the hub 3, to which the auxiliary dasher is attached,

surrounds the staff 1 and is held thereto by means of a set screw 5 threaded into an openin formed in a side of the hub 3.

ach of the Yarms 4 is provided with a rotary agitator 6 which is in the form of a propeller wheel, its axle 7 having detachable connection with an armr4. The arms 4 are uniformly disposed about the hub 3 with the result that the rotary agitato-rs 6 are evenly distributed about the stal 1. The ro- Y tary agitators 6 flare upwardly and converge downwardly towards the ordinaryY head of the dasher comprising the arms 2. The arms 4 have a pivotal arrangement which results in imparting a rotary movement to the agitators as the dasher is rey ciprocated.

It has been found that a dasher constructed in accordance with the present invention is rapid in operation and quickin action in breaking up the butter cysts, thereby greatly simplifying and reducing Vthe time usually required for churning.

' In Figure 4 of the drawings, a modified form oI' the hub is shown. This hub 3a is split, and it is secured in position upon the stall" 1 by means .of a bolt 8 which passes 1tlhripugh a pair of ears 9 carried by the What is claimed is:

1. A dasher comprising a spider including a hub, arms radiating from said hub and having their outer ends inclined upwardly in converging relation, and a rotary' agitator applied to the outer end of each of the arms and disposed to converge upwardly Aand ilare downwardly.

2.7A reciprocating' churn dasher comp-risinga staff and head and a plurality of rotary agitators grouped about the staff and carried thereby and disposed so as to flare downwardly and converge upwardly, said rotary agitators being positioned above saidV head and said head comprising laterally extending arms.

3. As a new article of manufacture, an attachment for al dasher, the same comprising a'collar to be tted about andsecured to a Vsus dasher staff, arms radiating from said colarota agitator appliedto the outer end of 10V lar, and a'rotary agitator carried at thefree each o the arms and disposed to converge end ofeacli of said arms. upwardly and lar'e downwardly.

4. As a new article of manufacture, an In testimony whereof I affix my signature attachment for a dasher, the same compris in presence of two witnesses.

ing a collar to be fitted about and secured JAMES B. GURNEY. to a dasher staff, arms radiating from said Witnesses: Y collar, said arms having their free ends in- HORACE HAWKINS,
